Question

what is rhizobial inoculation

Answer 1

Legumes growing together with soil bacteria called rhizobia work together to take atmospheric nitrogen N2 found in soil air spaces and transform or fix it into a plant-available form through the process called Biological Nitrogen Fixation.

Answer 2

Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes.

To express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen.

In general, they are gram negative, motile, non-sporulating rods.
